For family 'A' the total energy consumed in watt hour every day
`=(3xx5xx100)+(4xx8xx200)+(1xx3xx2500)+(1xx2xx2000)`
`=1500+6400+7500+4000=19400 ` w h.
The energy consumed in kilowatt hour (units) for 30 days
`=(19400xx30)/(1000)=582` units.
The electricity bill for April `= 582xx4=Ra. 2328`.
For family 'B' the total electrical energy consumed in watt hours every day
`=(4xx4xx100)+(5xx6xx200)+(1xx3xx2500)+(1xx2xx2000)`
`=1600+6000+7500+4000=19100 ` w h.
The energy consumed in kilowatt hour (units) for 30 days
`=(19100xx30)/(1000)=573` units.
The electricity bill for April `= 573xx4=Rs. 2292`.
